Personal Statement:

I am currently interested in identifying genetic DNA elements in the genes that may affect cancer risk or progression, and characterize their contributions individually, in conjuction and in combination with specific environmental factors (e.g. smoking, diet). Analyzing the biochemical effect of EPHX missense variants identified in colorectal cancer patients. Also, measuring the rate of genomic variation and the degree of genomic heterogeneity in cancer tissue, compared to normal adjacent tissue.
